EWJ Series High/Low Temperature & Humidity Test Chamber
طلب عرض سعر
Environmental simulation chamber for testing materials by simulating conditions at desired temperature and humidity levels
Sterilization function: (Not available for models 01 and ET)
Application: Allows the test chamber to be used for mold incubation tests.
Additional Components
- Ventilation system
- Ozone sterilization unit
Features
- Top-exhaust design with a compact, balanced layout that makes better use of space, reduces installation constraints, and limits the impact on ambient temperatures.
- Advanced noise reduction measures keep sound levels below 57 dB(A), similar to the volume of a normal conversation.
- Wide operating range for temperature and humidity with consistently reliable performance.
- High-precision control: temperature fluctuation within ±0.5 °C, temperature deviation within ±1.5 °C, and humidity deviation within ±3.0% RH.
- Incorporates industry-leading ELV electronic expansion valve technology, allowing intelligent compressor power adjustment that cuts energy consumption by about 30% compared to traditional thermal expansion valves while extending compressor lifespan.
Construction and Components
- Stainless steel rack can be repositioned to fit samples of different heights. For heavier loads, optional reinforced shelves are available, supporting up to 80 kg per tier.
- Side-mounted cable ports on both walls allow flexible connections for power or instrumentation from any direction. Multi-port configurations can also be customized to handle setups requiring a larger number of cables. Durable soft rubber plugs maintain a tight seal across a wide temperature range and have a long service life.
- A large, clear observation window with multi-layer tempered glass and an anti-condensation heating element makes it easy to monitor samples throughout testing without fogging.
- The interior is precision-welded with automated equipment and sealed using high-integrity gaskets to keep the chamber airtight.
- For water supply, a dual tank system combines a fixed reservoir and a removable handheld tank that can be refilled during operation without interrupting the test process.

For air-cooled models, performance specifications are based on an ambient temperature of 25 °C and relative humidity of ≤85% measured with the chamber empty. For water-cooled models, reference conditions are an ambient temperature between 15 °C and 35 °C, relative humidity of ≤85%, and cooling water temperature of ≤ 28℃, also measured without test samples inside the chamber.
